  fs-verity: support reading signature with ioctl (2021-02-07 14:51:19 -0800)

----------------------------------------------------------------

Add an ioctl which allows reading fs-verity metadata from a file.

This is useful when a file with fs-verity enabled needs to be served
somewhere, and the other end wants to do its own fs-verity compatible
verification of the file.  See the commit messages for details.

This new ioctl has been tested using new xfstests I've written for it.
